Critical issues: • Fully containable interior environment, to accommodate the extensive overhaul work required. • Subsequent use plans to enable hangar to accommodate B747, B777 or two narrowbody aircraft side by side. • Tight seal needed to negate the undulating apron area in front of hangar. • Independent goalpost frame, to suspend doors on and convey load to existing structure. • Flexible use, as well as energy efficiency. • Ability for the door to withstand potential cyclonic conditions. Megadoor provided: • Project and design collaboration with design architects, engineers and contractor. • Megadoor® vertical fabric folding door, total dimension 77 m wide, comprising five individually or jointly manoeuvrable leaves connected by swing-up mullions.
